Kotlin Program to Multiply Two Floating-Point Numbers

In this article, we will understand how to multiply two floating-point numbers. A floating-point number, is a positive or negative whole number with a decimal point. There are two types of floating point in Kotlin

• Float
• Double

Below is a demonstration of the same ?

Suppose our input is

val1: 10.5
val2: 45.0

The desired output would be

The product is: 472.5

Algorithm

• Step 1 ? Start

• Step 2 ? Declare three floating points: val1, val2 and product

• Step 3 ? Define the floating-point values

• Step 4 ? Read the values

• Step 5 ? Multiply the two values using a multiplication operator (*)

• Step 6 ? Display the result

• Step 7 ? Stop

Example 1

In this example, we will multiply two floating-point numbers using the multiplication arithmetic operator

fun main() {

   val val1 = 10.5f
   val val2 = 45.0f

   println("The first value is defined as: $val1")
   println("The second value is defined as: $val2")
   
   val product = val1 * val2
   println("The product is: $product")
}

Output

The first value is defined as: 10.5
The second value is defined as: 45.0
The product is: 472.5

Example 2

In this example, we will multiply two floating-point numbers:

fun product(val1 : Float, val2 : Float){
   val product = val1 * val2
   println("The product is: $product")
}

fun main() {
   val val1 = 12.5f
   val val2 = 40.0f

   println("The first value is defined as: $val1")
   println("The second value is defined as: $val2")
   product(val1, val2)
}

Output

The first value is defined as: 12.5

The second value is defined as: 40.0
The product is: 500.0

Example 3

In this example, we will multiply two floating-point numbers (Double) using the multiplication arithmetic operator

fun main() {
   val val1 = 12.0
   val val2 = 23.5

   println("The first value is defined as: $val1")
   println("The second value is defined as: $val2")

   val product = val1 * val2
   println("\nThe product is: $product")
}

Output

The first value is defined as: 12.0

The second value is defined as: 23.5
The product is: 282.0
